我正在研究获取应用程序日志并将其上传到服务器的功能。我们正在将日志写入文件。
我需要做什么?
我们已使用Fabric(当前为Firebase crashlystics)进行崩溃报告。但是有时候会错过很多崩溃。因此我们无法跟踪客户问题。我们决定实施自己的崩溃报告工具。我们决定在启动应用程序时上载日志,而不进行任何进一步的处理。应用崩溃后,崩溃报告将被写入文件,并且在下次启动应用时,该文件将被上传到服务器。我不想让用户陷入此类困境,因此我决定通过服务来做到这一点。所以我需要在应用程序启动时启动服务,并且日志应该在服务范围内上传到服务器,没有任何困难。如果在服务的下一行启动后应用程序崩溃,则该服务不应停止
我尝试了什么?
我已使用服务将日志上传到服务器。我试图在应用程序类onCreate()
上启动前台服务,该服务将在不同的进程上运行,并且按预期工作正常。但是问题在于,如果登录活动(第一个活动)onCreate()
发生崩溃,则前台服务未按预期启动。崩溃后服务进程停止。
我想要什么?
我想启动将日志上传到服务器的前台服务或意图服务。上传日志后,它将停止。同时,如果应用程序因其他原因崩溃,则服务不应停止,并且应完成其任务。

请问有人可以提出解决方案吗?还是更好的方法呢?
